Looking to buy a new portable AC unit with an accessible app. Also would appreciate a check on tactile buttons. Here's what I found:
Honeywell uses the Residio app, which I have. Accessible text but the usual labelling annoyances: no selected indicator on things that need selecting, while all buttons on some other screens say "selected" when there's nothing to select. But I'll probably get this one.
Whynter: uses the NetHome Plus app. All helpful app store reviews are 1-star, while all the positive/recent reviews appear to be fakes--one liners by what appear to be non-native English speakers. I own a Whynter now and it has tactile buttons and puts out massive amounts of cold air as well as hot air in heat mode.
Fridigair: the Frigidair app gets very poor recent reviews.
LG: Same as for NetHome. Recent reviews combine lots of 1-stars with 5-star reviews that are all a few words long with poor grammar. That's for the ThinQ app. Don't know if that's for portable ACs.
